1 LEGIONELLA CONTROL POLICY Originator: Policy and Strategy Team Approval date: August 2018 Review date: August Introduction Pine Court Housing Association (PCHA) treats the health and safety of tenants, staff, contractors and other users of its buildings of paramount importance. In meeting its health and safety duties, PCHA will ensure it has in place effective and comprehensive measures to prevent or control the spread of Legionellosis (including legionnaires disease). Legionnaires disease is a potentially fatal pneumonia caused by Legionella bacteria and is the most serious form of a group of diseases known as Legionellosis. Legionella bacteria are common in natural water sources and can if the right conditions exist (usually temperatures between C and where there is a supply of nutrients such as rust, sludge, scale, algae and other bacteria in a bio-film ) proliferate in artificial water systems, capable of producing an aerosol or water vapour. This Policy sets out the measures PCHA puts in place to assess the risks posed by Legionella bacteria and the control systems established to mitigate or eradicate these risks as far as is reasonably possible. This Policy also sets out PCHA s responsibilities to comply with the relevant legislation and associated regulatory guidance on the control of Legionella bacteria in water systems. The principal legislation in this area is as follows: BS8580: 2010 Water Quality Risk Assessments for Legionella Control Code of Practice ACOP- L8 The Control of Legionella Bacteria in Water Systems Approved Code of Practice and Guidance 2013, Part 2&3 Health and Safety at Work Act 1974 The Management of Health and Safety at Work Regulations 1999 Control of Substances Hazardous to Health Regulations 2002 The Public Health (Infectious Diseases) Regulations 1988 The Water Supply (Water Fittings) Regulations 1999

2 The Water Supply (Water Quality) Regulations 2010 BS 6700:2006 Specification for Design, Installation, Testing and Maintenance of Services Supplying Water For Domestic Use Within Buildings and their curtilages 1.5 The application of this Policy ensures that PCHA complies with the outcomes of the Regulatory Framework for Social Housing in England as follows: Treat all tenants with fairness and respect Demonstrate that they understand the different needs of their tenants, including in relation to the equality strands and tenants with additional support needs Provide a cost-effective repairs and maintenance service to homes and communal areas that responds to the needs of and offers choices to tenants and has the objective of completing repairs and improvements right first time, meet all applicable statutory requirements that provide for the health and safety of the occupants in their homes 1.6 The Policy meets the following PCHA corporate aims: To provide homes that meet demand in safe and sustainable neighbourhoods To provide excellent services that meet or exceed customers and stakeholders expectation Access and Communication PCHA is committed to ensuring that the services it provides are accessible to everyone. PCHA will seek alternative methods of access and service delivery where barriers, perceived or real may exist, that may make it difficult for people to work for PCHA or use its services. Equality, Diversity and Human Rights PCHA is committed to ensuring that no person or group of persons will be treated less favourably than another person or group of persons and will carry out its duty with positive regard for the following core strands of equality; Age, Disability, Gender, Race, Transgender, Sexual Orientation, Pregnancy and Maternity, Marriage and Civil Partnership, Religion and/or Belief. PCHA also recognises that some people experience disadvantage due to their socio-economic circumstances, employment status, class, appearance, responsibility for dependants, unrelated criminal activities, being HIV positive or with AIDS, or any other matter which causes a person to be treated with injustice. PCHA will also ensure that all services and actions are delivered within the context of current Human Rights legislation and will make every effort to ensure staff and others with whom PCHA works, will adhere to the central principles of the Human Rights Act (1998). This Policy forms part of a suite of Policies known collectively as Compliance Policies and includes: The PCHA Gas Safety Policy The PCHA Asbestos Management Policy

3 The PCHA Fire Safety Policy The PCHA Lift Maintenance Policy The PCHA CCTV Policy The PCHA Electrical Gates Policy Periodic Electrical Testing Policy 2 Statement of intent PCHA will comply with all legal and regulatory requirements in meeting its responsibilities to prevent and control the proliferation of Legionella bacteria from artificial water systems in buildings it owns and controls. PCHA will appoint a Competent Person (see Section for 3.2 details) to identify and assess risks from Legionella bacteria in PCHA owned and controlled buildings and carry out a comprehensive risk assessment in conjunction with suitably qualified contractors. Having established a baseline position of equipment and services that pose a reasonably foreseeable risk of proliferation of Legionella bacteria, the Competent Person will devise a control scheme to manage and mitigate any risks identified including appropriate testing regimes, treatment methods and general design and installation considerations. PCHA will co-operate fully with any emergency planning contingencies and investigations by Local Authorities and Health and Safety Executives in the areas of its operation, in the unlikely event of any major Legionella outbreak in or affecting buildings it owns and controls. 3 Policy Duty Holders Responsibilities PCHA as the owner of properties and buildings where artificial water systems are present, will have responsibility to identify and manage the risks posed by Legionella bacteria. The Director of Assets) fulfils the role of Duty holder for PCHA with direct line management over the Competent Person, the Compliance Manager. The Competent Person will provide regular reports to the Duty Holder and the Strategic Health and Safety Group on the operation of the Legionella control system and to the PCHA Executive Management Team, as required by any major incidents. Competent Person Responsibilities The Competent Person, the Compliance Manager (who will be the Responsible Person for Legionella Management and Control of building hot and cold water services P901 qualified) and a suitably experienced and qualified deputy, the Compliance Officer (also P901 qualified) will work in conjunction with the Appointed Specialist Contractors to carry out risk assessments, which as a minimum will establish the following risk factors: The presence of Legionella bacteria If conditions are present that will encourage bacteria to multiply (see 1.2)

4 If it is possible that water droplets i.e. an aerosol can be produced which could be dispersed over a wide area If it is likely that anyone considered to be more at risk (those over 45, smokers and heavy drinkers, those suffering chronic respiratory or kidney disease) will come into contact with contaminated water droplets The potential for scalding (from heating water above 60 C to kill Legionella bacteria) When assessing water systems in PCHA properties and buildings that are likely to pose a risk from the proliferation of Legionella bacteria, the risk assessment will focus on the following: The source of the system supply water, for example, whether from a mains supply or not Possible sources of contamination of the water supply The normal operating conditions of the equipment or system Unusual, but reasonably foreseeable operating conditions such as breakdowns The Competent Person, will ensure that the risk assessment process is periodically dependent on the current risk rating of the building or if there are significant changes to water systems or their use, including the addition of new buildings to the PCHA portfolio or: The availability of new information about risks or control measures that is issued from the Health and Safety Executive, or to stay in line with best practice The results of inspections indicate that control measures are no longer effective A case of Legionellosis is associated with a water system in PCHA s control The Competent Person will use the risk assessment process to inform the operation of a Control Scheme, which sets out the necessary precautions to: Prevent the growth of Legionella bacteria including: o The avoidance of water temperatures that favour proliferation of Legionella bacteria and other micro-organisms o The avoidance of water stagnation (tank cleaning to prevent bio-films forming, removing dead legs and redundant pipework where required) o The avoidance of the use of materials that harbour bacteria and other microorganisms, or provide nutrients for microbial growth and complying with the Water Fittings and Materials Directory for plumbing fittings and water appliances: Controlling the release of water spray Maintaining the cleanliness of the system and water in it Using water treatment techniques Taking action to ensure the correct and safe operation of the water system Operate control measures to treat water in systems (to be determined in conjunction with the Appointed Specialist Contractor, which includes cleaning and disinfection, chemical disinfection and thermal disinfection, as required) Ensure the correct use of and maintenance of systems (including provision of work instructions for operatives carrying out maintenance tasks and in conjunction with the

5 Health and Safety Team, ensuring appropriate signage is in place to prevent scalding incidents) The Competent Person will carry out an annual audit of the Control Scheme to assess its effectiveness and the competence of the Appointed Specialist Contractors, ensuring they have been issued with the Legionella Control Association s Recommended Code of Conduct. Specialist Appointed Contractors Responsibilities PCHA will employ an Appointed Specialist Contractor to carry out periodic inspections and monitoring (including sampling and testing) of PCHA s water systems in accordance with the requirements of the Control Scheme. The Appointed Contractor, in close liaison with the Competent Person will administer any control measures required to mitigate the risks of Legionella bacteria and will supply PCHA with recommendations for any remedial works identified during periodic inspections. The Competent Person will arrange for remedial works to be carried out by PCHA s contractors or may depending on the nature and technical complexities of the works identified, instruct the Appointed Specialist Contractor to carry out the remedial works. The Appointed Contractor will carry out an annual internal audit of their own operations and will provide a report to the Competent Person and assurances that they continue to hold and comply with all the requirements of the Legionella Control Association s Recommended Code of Conduct. Void Properties PCHA will operate robust measures to reduce the risk of Legionella in void properties due to stagnant water systems. The Competent Person or their Deputy will liaise with the Neighbourhood Services Team to implement a regime of flushing water systems in all long-term empty properties on weekly basis, until they are occupied. PCHA will keep all records for the flushing work on all void properties The Appointed Contractor will take samples for analysis and if results of a sample are not satisfactory, the system will be cleaned, disinfected and re-sampled PCHA will ensure that water systems in all long-term void properties are drained, cleaned and disinfected prior to re-use Communication PCHA will ensure clear lines of communication are established and are effective at all times. The Competent Person (or Deputy if not available) will communicate regularly with the Specialist Appointed Contractor (normally on a monthly cycle or more immediately as required). At a minimum the following issues will be discussed: The Competent Person to inform the Appointed Contractor of any changes or additions to the water systems in PCHA properties requiring inclusion on the Control Scheme

6 The Appointed Contractor to inform the Competent Person of any remedial actions required as a result of inspection or any other significant matters affecting the control of Legionellosis The Appointed Contractor will provide PCHA with a monthly report of all Legionella management activities undertaken on PCHA Properties. The Compliance Manager will discuss any exception circumstances with the Head of Health & Safety and Compliance If during routine checking Legionella bacteria are found at levels which pose a risk to health and safety or there are confirmed outbreaks of Legionellosis in areas where PCHA has properties, communication between the Specialist Appointed Contractor, the Competent Person and the PCHA Executive Management Team (EMT) will take effect at the earliest opportunity. Record Keeping The Competent Person will be responsible for ensuring appropriate records are kept for all measures associated with PCHA s management of Legionellosis. In accordance with the Health and Safety Executive Accepted Code of Practice, records will be kept of the following: The names and positions of all people carrying out tasks within the PCHA Control Scheme The risk assessment and Control Scheme (which will be updated with each action, addition or alteration) Plans or schematics of the areas, equipment and systems covered in the PCHA Control Scheme Details of any control or precautionary measures undertaken by the Specialist Appointed Contractor or PCHA operatives Details of all remedial work carried out All visits by contractors, consultants and other personnel associated with the operation of PCHA s Control Scheme Cleaning and disinfection procedures and associated reports and certificates Results of all sampling and testing undertaken Details of all chemical / biological treatments used in control measures All training provided to operatives and the Competent Persons that play a role in PCHA s Control Scheme and overall arrangements for Legionellosis management (to be retained by the People and Learning Team) Details of the current state of operation of PCHA s water systems that could pose a risk of Legionellosis bacteria and any periods where they are inactive and require draining down All retained records kept be dated and signed or show some other form of authorisation from the person carrying out the actions e.g. inspections will be signed by the Appointed Specialist Contractor s Operative(s). Records will be kept electronically within the Appointed Specialist Contractor s systems and will be retained for a minimum period of two years and five years for any records relating to monitoring, inspection, tests or checks. The Competent Person and Deputy will have viewing access and can provide viewing access to other interested parties, on request.

7 Actions in the event of a Legionellosis Outbreak Should an outbreak of Legionellosis occur (defined by the Public Health Laboratory Service (PHLS) as two or more confirmed cases of Legionellosis occurring in the same locality within a six month period), the Head of Health & Safety and Compliance will: Liaise with the Proper Officer from either the Local Authority or the Local Health and Safety Executive who will invoke an Outbreak Committee Inform the PCHA Executive Management Team and Appointed Specialist Contractor at the earliest opportunity Comply with all requests for information / actions required to control an outbreak including shutting down of systems, cleaning or treatment works as required by the Outbreak Committee Ensure the Outbreak Committee receives information relating to staff sickness records to determine if there are any undiagnosed cases of Legionellosis related illness 4 Implementation All PCHA staff have a responsibility for ensuring buildings owned or controlled by PCHA have adequate protection from the risks of Legionellosis bacteria proliferation as part of the general requirements to comply with Health and Safety regulations. Whilst not all staff will have specific duties in regard to Legionellosis control measures, they will need to have an awareness of the Policy to deal with any customer enquiries that may arise. The Competent Person and Deputy will have overall responsibility for ensuring PCHA has in place adequate measures to eradicate or control risks from Legionellosis bacteria (see section 3.2 for specific responsibilities). 5 Performance 5.1 There are no additional performance requirements as a result of this Policy. 6 Consultation The Customer Empowerment Panel was consulted in the development of this Policy. Specific input of technical advice has been sought from those staff with operational knowledge of Legionellosis control management. 7 Review 7.1 The Policy will be reviewed every 12 months from the date of the Operations Director s (PCHA) approval to ensure its continuing suitability, adequacy and effectiveness or as required by the introduction of new legislation or regulation that impacts on the Legionellosis management obligations of PCHA, changes to PCHA business practices or in light of management system audits.
